female gave male unprotected oral sex

[mm484]

Hello!
I am a 23 year old white female and I recently gave unprotected oral sex to a 24 yearold white male I go to college with.  This happened in South Eastern Washington State. He has not been incarcerated and he does not do drugs or have sex with men as far as I know considering I am not with him 24-7.  He lives with his girlfriend of 3 years who he plans to marry.  I sucked on his penis for several minutes and he did not ejaculate in my mouth.  What I am afraid of is that I licked the tip of his penis and I probably got some of his precum on the tip of my tongue which could have soaked into my tongue. I was tested for HIV six months ago which was negative six months ago. When I asked him how many girls he had slept with in the past he said "quite a few" between the ages of 17 and 21- when he met his girlfriend. Do you think I could have HIV from this? I do not want to get tested because I have a higher chance of a false positive than of having HIV but I always worry! I have been having canker sores on my tongue. I am engaged to be married and I did this activity as a last hoorah before I got married but I regret it daily.  
Thanks doctor! You mean a lot to so many people

If you decide to get tested, you are ding so for your peace of mind, not for a medical indication.  I am confident that hsould you get tested the result will be negative.  EWH

One more thing- I noticed on some of your comments to others you say to get tested if a negative result will help you sleep better meaning that if I am okay with your answer I can safely skip the test and that I only need it for psychological purposes. I know there are no absolutes in life but your previous answer implys that I will have a negative result correct?  This is my final question!

Thank you Doctor Hook,

This does help me feel better. I am graduating from college, just got a house, getting married and I had a negative test six months ago and I have high anxiety that I ruined it all, plus I had chlamydia a year ago which makes me even more anxious about catching things. My canker sores have not cleared up so that made me nervous but I know for sure that symptoms mean nothing. I feel relieved that I do not have hiv from this encounter and I am now ready to commit myself to only ONE person in marraige and I have learned a lesson from this.  Thank you, thank you!

I hope that I can help to relieve your concerns.  There is virtually no risk from the exposure you report.  I say this with confidence based on the statistics related to the risk of your exposure.  Those statistics include:
1.  Your partner was low risk, even though he had multiple prior partners.  Odds of him being infected are less than 1 in 1000.
2.  Even if he was infected, the quoted figure for HIV risk, if one has oral sex with an infected partner is less than 1 in 10,000 and, in my estimation that is too high. Some experts state there is no risk at all from oral sex.  Neither of us on this site have ever seen or reading the medical literature of a convincing instance in which HIV was passed by oral sex.  

Just putting these two numbers together, your odds of infection are less than 1 in 10 million - not something to worry about.  

Finally, if you wish to get tested do so.  You are right that your odds of a false positive are higher than your risk of being infected but, at the same time, even that risk is tiny.  Do not let fear of false positives keep you from getting an HIV blood test if it would comfort you.  Remember the CDC has recommended that all Americans, high or low risk for HIV get tested at least once.  I agree with this recommendation.  

Hope this helps.  Take care.  EWH
